  *           + Initialization and de-initialization functions.
  *           + Start/Stop operation functions in polling mode.
  *           + Start/Stop operation functions in interrupt mode.

  ==============================================================================
                     ##### How to use this driver #####
  ==============================================================================
    [..]
      The LPTIM HAL driver can be used as follows:

      (#)Initialize the LPTIM low level resources by implementing the
        HAL_LPTIM_MspInit():
         (##) Enable the LPTIM interface clock using __LPTIMx_CLK_ENABLE().
         (##) In case of using interrupts (e.g. HAL_LPTIM_PWM_Start_IT()):
             (+++) Configure the LPTIM interrupt priority using HAL_NVIC_SetPriority().
             (+++) Enable the LPTIM IRQ handler using HAL_NVIC_EnableIRQ().
             (+++) In LPTIM IRQ handler, call HAL_LPTIM_IRQHandler().

      (#)Initialize the LPTIM HAL using HAL_LPTIM_Init(). This function
         configures mainly:
         (##) The instance: LPTIM1.
         (##) Clock: the counter clock.
             (+++) Source   : it can be either the ULPTIM input (IN1) or one of
                              the internal clock; (APB, LSE or LSI).
             (+++) Prescaler: select the clock divider.
         (##)  UltraLowPowerClock : To be used only if the ULPTIM is selected
               as counter clock source.
             (+++) Polarity:   polarity of the active edge for the counter unit
                               if the ULPTIM input is selected.
             (+++) SampleTime: clock sampling time to configure the clock glitch
                               filter.
         (##) Trigger: How the counter start.
             (+++) Source: trigger can be software or one of the hardware triggers.
             (+++) ActiveEdge : only for hardware trigger.
             (+++) SampleTime : trigger sampling time to configure the trigger
                                glitch filter.
         (##) OutputPolarity : 2 opposite polarities are possibles.
         (##) UpdateMode: specifies whether the update of the autoreload and
              the compare values is done immediately or after the end of current
              period.

      (#)Six modes are available:

         (##) PWM Mode: To generate a PWM signal with specified period and pulse,
         call HAL_LPTIM_PWM_Start() or HAL_LPTIM_PWM_Start_IT() for interruption
         mode.

         (##) One Pulse Mode: To generate pulse with specified width in response
         to a stimulus, call HAL_LPTIM_OnePulse_Start() or
         HAL_LPTIM_OnePulse_Start_IT() for interruption mode.

         (##) Set once Mode: In this mode, the output changes the level (from
         low level to high level if the output polarity is configured high, else
         the opposite) when a compare match occurs. To start this mode, call
         HAL_LPTIM_SetOnce_Start() or HAL_LPTIM_SetOnce_Start_IT() for
         interruption mode.

         (##) Encoder Mode: To use the encoder interface call
         HAL_LPTIM_Encoder_Start() or HAL_LPTIM_Encoder_Start_IT() for
         interruption mode.

         (##) Time out Mode: an active edge on one selected trigger input rests
         the counter. The first trigger event will start the timer, any
         successive trigger event will reset the counter and the timer will
         restart. To start this mode call HAL_LPTIM_TimeOut_Start_IT() or
         HAL_LPTIM_TimeOut_Start_IT() for interruption mode.

         (##) Counter Mode: counter can be used to count external events on
         the LPTIM Input1 or it can be used to count internal clock cycles.
         To start this mode, call HAL_LPTIM_Counter_Start() or
         HAL_LPTIM_Counter_Start_IT() for interruption mode.

      (#) User can stop any process by calling the corresponding API:
          HAL_LPTIM_Xxx_Stop() or HAL_LPTIM_Xxx_Stop_IT() if the process is
          already started in interruption mode.

       (#)Call HAL_LPTIM_DeInit() to deinitialize the LPTIM peripheral.
